avoid_ empty_ else
Learn about the avoid_empty_else linter rule.
Avoid empty statements in else clauses.
Details
#
AVOID empty statements in the
else clause of if statements.
BAD:
if (x > y)
print('1');
else ;
print('2');
If you want a statement that follows the empty clause to
conditionally run, remove the dangling semicolon to
include it in the else clause. Optionally, also
enclose the else's statement in a block.
GOOD:
if (x > y)
print('1');
else
print('2');
GOOD:
if (x > y) {
print('1');
} else {
print('2');
}
